Currently in web if you need to adjust an AR Invoice that has several projects for the distribution breakdown for the total of the invoice and you only want to change 1 of them, the system triggers an error. For example, AR Invoice $10 broken down Proj X $5 Proj Y $5. The invoice needs to change to $9 and only Proj X change to $4 no change to Proj Y. The system doesn't allow you to only change the 1 line.
